Android Build System^[1]

The Android Build System, similarly to Buildroot, is a set of build scripts (.mk files, bash scripts) used to build Android.

At the root of the Android Build System, the first thing to do is to set-up the environment: source build/envsetup.sh.

Thus, commands will be available to start the build.
